Why didn't economists see it coming?

I've been getting plenty of questions from colleagues and students at school on why wasn't this crisis averted earlier. The "Subprime crisis" explanation by The Long Johns" was after all uploaded on youtube in January!

Well, Paul Krugman offers his view in a most elegant (as usual) way in today's NYT:
"Some people say that the current crisis is unprecedented, but the truth is that there were plenty of precedents, some of them of very recent vintage. Yet these precedents were ignored. And the story of how “we” failed to see this coming has a clear policy implication — namely, that financial market reform should be pressed quickly, that it shouldn’t wait until the crisis is resolved.

About those precedents: Why did so many observers dismiss the obvious signs of a housing bubble, even though the 1990s dot-com bubble was fresh in our memories?

Why did so many people insist that our financial system was “resilient,” as Alan Greenspan put it, when in 1998 the collapse of a single hedge fund, Long-Term Capital Management, temporarily paralyzed credit markets around the world?

Why did almost everyone believe in the omnipotence of the Federal Reserve when its counterpart, the Bank of Japan, spent a decade trying and failing to jump-start a stalled economy?

One answer to these questions is that nobody likes a party pooper. While the housing bubble was still inflating, lenders were making lots of money issuing mortgages to anyone who walked in the door; investment banks were making even more money repackaging those mortgages into shiny new securities; and money managers who booked big paper profits by buying those securities with borrowed funds looked like geniuses, and were paid accordingly. Who wanted to hear from dismal economists warning that the whole thing was, in effect, a giant Ponzi scheme?"
